iPhone 3G Activate Iphone 3G from HK

I bought a iphone 3G from HongKong and try to use it in China (china mobile).
It does not find network; thus impossible to make calls.
I thought it was related to the activatation; then i install and synchronise with Itunes 8.
Still do not find network.

I wish I had one to play with but I don't have one yet. I would maybe try a factory restore and possible a new SIM.

Just did a quick search and found this:

"Culture aside, China Mobile's 3G technology could also cause problems for Apple. The carrier is using the TD-SCDMA standard for 3G data access, but the iPhone 3G doesn't support it. If China Mobile were to distribute the iPhone, Apple would either need to switch 3G chips or produce special iPhones for the Chinese market. China Telecom and China Unicom both have plans to use 3G standards that the iPhone already supports (CDMA2000 and WCDMA, respectively), making them even more attractive to Apple." (Source)

It might be a problem with China Mobile and not the iPhone. I'd maybe try to find a different carrier SIM.

the phone is not lock so i am not supposed to use a magic sim card.
i am not sure whether it is related to the activation on Itunes .
I have connected the phone on I tunes but still impossible to have network and make calls.
